This rotary control is used to switch the preamp from 2
channel active mode to 6 channel passive mode.
Volume must be all the way down when switching to or from
2 and 6 channel mode.
2Channel Mode (AC or DC mode)
When in the 2 channel mode the preamplifier can be used
in the AC/DC mode for active gain. This mode utilized the
inputs marked 1,2,3 on the back panel and then routes the
signal to the main outputs. Turn off your processor when in
the 2 channel mode otherwise you could have audio going
to your center or rear speakers.
6 Channel Mode (AC mode only)
When the preamplifier is switched to 6 channel mode it uti-
lizes the Front, Rear, and Center inputs on the back panel.
This mode is passive and does not route through the gain
stage of the preamplifier. It is purely passive and goes
through the discrete 6 channel volume control. Individual
channel gain is set in the surround processor and overall
volume level is then done by the preamplifier. The pream-
plifier automatically switches between the inputs and
outputs in this mode. The 6 channel mode is purely
passive. There is no need for the DC mode while in the 6
channel mode. When switching out of the 6 channel mode
back to 2 channel mode it is very important to make sure
the volume level is all the way down, otherwise you could
damage your speakers or amplifier.
In the 6ch mode the preamplifier can be used as a Passive
Only Preamp (no gain) by using the Front inputs and the
Main Front outputs on the back panel. Be sure the mode
switch is on 6 channel to use it passively.
The volume will go up or down from the remote or
manually in any mode. It is very important to turn
the volume down before switching to or from
2 or 6 channel modes.
